Challenges faced by Law
Enforcement
Awareness:
Technical Issues:
Software and Hardware Issues:
Information sharing:
Inadequate Training and Funds:
Global Issues:
Wireless or Wi-Fi, Bluetooth, Infrared Issues:

PREVENTION
Disable and log off a specific user account to
prevent access.
Disable and log off a group of user accounts
which access a particular service that is being
attacked.
Disable and dismount specific (network)
devices, for instance disk devices that are
being swamped.
Disable specific applications, for example, an
e-mail system subjected to a SPAM attack.
Close down an entire system, and divert

Insert firewalls.
Uninstall unnecessary software
Maintain backup.

Stay anonymous - choose a genderless screen

CONCLUSION
Obviously computer crime is on the rise, but so is
the awareness and ability to fight it. Law
enforcement realizes that it is happening more
often than it is reported and are doing there best
to improve existing laws and create new laws as
appropriate. The problem is not with the
awareness or the laws, but with actually reporting
that a crime has occurred. Hopefully people will
begin to realize that unless they report these
crimes and get convictions, those committing
computer crimes will continue to do so.
